A microbial process for the destruction of acetonitrile has been developed. Suitable microorganisms were enriched from activated sludge by cultivation with a high selection pressure when acetonitrile was the sole source of carbon and nitrogen. The process is based on cultivating the microorganisms as a biofilm on plastic carriers. These are utilised in a stirred-tank reactor with continuous feedin
This article describes results of the work on knowledge representation techniques chosen for use in the European project SIARAS (Skill-Based Inspection and Assembly for Reconfigurable Automation Systems). Its goal was to create intelligent support system for reconfiguration and adaptation of robot-based manufacturing cells. Declarative knowledge is represented first of all in an ontology expressed
Popular Abstract in Swedish Polycykliska aromatiska kolväten (PAH) är en grupp organiska ämnen som kan vara giftiga men även starkt cancerframkallande. De bildas vid förbränning av organiskt material vid låg syretillförsel och återfinns i olika produkter som tjära och fossila bränslen. De källor som tillför störst mängd till miljön idag är bostadsuppvärmning med ved, kol och olja (i Sverige ca 2/3Polycyclic aromatic hydrocarbons (PAHs) are a group of organic pollutants of great environmental concern, due to their toxicity, carcinogenicity and long persistence in the environment. To determine the potential risk associated with PAHs released from contaminated soil or waste materials, knowledge is required on the leachable concentrations of PAHs and the amounts available for release. The obj
Operative treatment for distal radius fractures continues to evolve, but small-fragment fixation has some advantages compared with previous methods. We assessed two groups of patients. Group 1 was an initial series of patients treated with small-fragment fixation at a large institution in the United States, and Group 2 was a review of patients treated in Lund, Sweden. The first group was evaluated
A previously developed biosensor for fast estimation of short-term biochemical oxygen demand (BODst) was used for off-line monitoring of intermediate products from the initial step of an anaerobic process in laboratory scale. Good agreement was generally achieved between the results from the biosensor method and the conventional 5-day test except for samples with high content of organic polymers.
We demonstrate experimentally and numerically that an x-ray prism made of beryllium can be used to disperse and monochromatize x-rays. A polished beryllium cuboid was employed as refractive and dispersive optics. The results of a proof-of-principle experiment and methods of performance optimization are presented. The spatial separation of undulator harmonics and their subsequent selection using a
In voltage- and temperature-biased coherent conductors quantum screening effects occur if the conductor's transmission is energy dependent. Here, we show that an additional ac-driven terminal can act as a probe for a direct readout of such effects, hitherto unexplored. We find that screening of charges induced by the static biases impacts already their standard linear thermoelectric response coeff
Characterisation of the AV-node is an important step in determining the optimal form of treatment for supraventricular tachycardias. To integrate and analyse patient-specific measurements, mathematical modelling has emerged as a valuable tool. Here we present a model of the human AV-node, consisting of a series of interacting nodes, each with separate dynamics in refractory time and conduction del
Non-negative matrix approximation (NNMA) has been used in diverse scientific fields, but it still has some major limitations. In the present study a novel trilinear decomposition method, termed three-way NNMA (TWNNMA), was developed. The method decomposes three-way arrays directly without unfolding and overcomes the restriction of locking zero elements in the deduced multiplicative update rules by
Atrial fibrillation (AF) is the most common heart arrhythmia, characterized by the presence of fibrillatory waves (f-waves) in the ECG. We introduce a voting scheme to estimate the dominant atrial frequency (DAF) of f-waves. Methods: We analysed a subset of Holter recordings obtained from the University of Virginia AF Database. 100 Holter recordings with manually annotated AF events, resulting in
Quantum entanglement between the degrees of freedom encountered in the classical world is challenging to observe due to the surrounding environment. To elucidate this issue, we investigate the entanglement generated over ultrafast timescales in a bipartite quantum system comprising two massive particles: a free-moving photoelectron, which expands to a mesoscopic length scale, and a light-dressed a
Halomonas boliviensis is a moderate halophilic bacterium, isolated from a soil sample around a hypersaline lake Laguna Colorada in the Andean region of Bolivia. The organism is capable of growing over a wide range of NaCl concentration (0-25 %, w/v), however with an optimum of about 4.5 % (w/v) NaCl. It is able to accumulate two useful products: poly(3-hydroxybutyrate) (PHB) and ectoines (ectoine
The dispersion-scan technique (d-scan) is a well-established technique for the measurement of ultrashort laser pulses. While a single-shot version of d-scan is relatively easy to implement for sub-10 fs laser pulses, this becomes increasingly difficult as the pulse duration increases due to the need for a larger dispersion range, which scales quadratically with the Fourier transform limit (FTL).

Identification of genes controlling complex diseases has proven to be difficult; however, animal models may pave the way to determine how low penetrant genes interact to promote disease development. We have dissected the Cia5/Eae3 susceptibility locus on mouse chromosome 3 previously identified to control disease in experimental models of multiple sclerosis and rheumatoid arthritis. Congenic strai
This article deals with an important question of legal justification: What reasons serve to justify a claim that a norm has the status of jus cogens. This question can be approached from two fundamentally different perspectives – in this article referred to as legal positivism and legal idealism. As earlier research has demonstrated, legal positivists have great difficulty justifying their jus cog

Genome-wide significant loci for metformin response in type 2 diabetes reported elsewhere have not been repli-cated in the Diabetes Prevention Program (DPP). To as-sess pharmacogenetic interactions in prediabetes, we conducted a genome-wide association study (GWAS) in the DPP. Cox proportional hazards models tested associations with diabetes incidence in the metformin (MET; n = 876) and placebo (P
